    job control: introduce JOBCTL_PENDING_MASK and task_clear_jobctl_pending() · 3759a0d9

    This patch introduces JOBCTL_PENDING_MASK and replaces
    task_clear_jobctl_stop_pending() with task_clear_jobctl_pending()
    which takes an extra @mask argument.
    
    JOBCTL_PENDING_MASK is currently equal to JOBCTL_STOP_PENDING but
    future patches will add more bits.  recalc_sigpending_tsk() is updated
    to use JOBCTL_PENDING_MASK instead.
    
    task_clear_jobctl_pending() takes @mask which in subset of
    JOBCTL_PENDING_MASK and clears the relevant jobctl bits.  If
    JOBCTL_STOP_PENDING is set, other STOP bits are cleared together.  All
    task_clear_jobctl_stop_pending() users are updated to call
    task_clear_jobctl_pending() with JOBCTL_STOP_PENDING which is
    functionally identical to task_clear_jobctl_stop_pending().
    
    This patch doesn't cause any functional change.
